Funny, my aux fan isn't working either. No overheating whatsoever, but the A/C doesn't work well until the engine warms enough for the clutch fan to start pulling air.

I'm still not sure if it's the fan, or relays etc. Something I have to troubleshoot this weekend. But I did find something interesting on the Realoem site that I'm hoping could be the issue rather than a dead fan.

Notice item number 6 describes a "repair kit resistor". Beetos, do you think maybe you wiped out the fan resistor with your battery fiasco? Does anyone else have experience with these fan resistors? Man, I'd sure rather drop $45 on this rather than replace that fan.

Oh and btw... how the hell do you get to it if you have to yank it anyway?!? The bentley manual goes over troubleshooting lightly, but mentions nothing on R&R. I'm guessing you'd have to yank the grille and the air dam underneath the bumper and pull it down/out that way. Who's done this before?

Thanks all!
